When i work in Unix environment such as HP-UX, IBM AIX, Linux, or Solaris; it is very important to be able to edit files. The file could be configuration file, scripts, or just note. I still remember some command of vi after long time not using it (more than 1 year) by limiting to remember only certain important command of vi. I think no need to master vi. Also don’t expect to use easy editor such as pico editor I got 5 years ago in FreeBSD environment, be familiar with vi is a must for people who take care of Unix system.
